> Do you have evidence that the standard coding interview works?

No, I think that they are all garbage.

The only way to really hire is by having a vibe check to see if they are someone the team wants to work with, making sure that the person seems competent and has a reasonable chance of being very productive, and then hiring them quick. Give them a month and if they don't seem like a good fit, then fire them, with 2 months severance.

This is the only way I've seen that will produce a great team quickly, by hiring quickly and firing quickly. This is similar to what Netflix does but they also pay top of market which not too many companies can afford, but it produces the best results.

I can't say this has ever been an issue for me. Generally, they just want to sell me some coffee.
A faster and more power hungry SoC can finish the task with better work done per joule if it is fast enough to offset the extra power consumption. It is my understanding that this is often not the case. See e.g efficiency cores compared to performance cores in these heterogeneous design; the E cores can get more done per joule AFAIU. If my understanding is correct, then removing the P cores from the M4 chip would let it get more work done per joule.

Regardless, the environmental impact I'm thinking about isn't mainly power consumption.
I've been saying this for years, I would love to get a desktop Mac and use an iPad for the occasional bit of portable development I do away from a desk, like when I want to noodle on an idea in front of the TV.

I'm very happy with my MacBook, but I don't like that the mega expensive machine I want to keep for 5+ years needs to be tied to a limited-life lithium battery that's costly and labour intensive to replace, just so I can sometimes write code in other rooms in my house. I know there's numerous remote options but...the iPad is right there, just lemme use it!
When it comes to London, the 'burbs' means get into a crowded train (or wait for the next, or the one after that as they are packed in many stations) AND spend 2h per day commuting (+ the very expensive fares). As a young professional in London I would prefer to have a nice 30-40sqm (~300-400 sqf) studio in the center, close to a market/park and be 20mins door-to-door to my work.

If one of the mega-big buildings would be converted to studios, meaning they could 'slice' 20-30 studios per floor, keep one floor for gym/dry cleaners/etc. they would be making a (financial) killing.
Sometimes having the ability to hold two conflicting ideas in one’s mind at the same moment is advantageous.
Car factories that make ICE vehicles can be switched to produce electric vehicles. The job losses in car plants you hear about are regional and caused by plants been moved to areas with cheaper workers and weaker labour law (Mexico for example).

It depends what you're trying to do, but I was essentially following this guide: https://rancher.github.io/elemental-toolkit/docs/examples/em... updated to ghcr.io/rancher/elemental-toolkit/elemental-cli:v1.3.0 / registry.suse.com/suse/sle-micro-rancher/5.4

The whole project is in major flux now though, with v1.3 -> v2.1 being pre-release and docs haven't been updated, so I'm waiting for dust to settle before picking it back up. But basically `docker build` -> `elemental build-disk` -> qcow2/iso -> deploy / `elemental upgrade` update via OCI registry, or deploy vanilla image and then just update that via registry.

Reality and I have had a pretty tough relationship, I'll concede that. I think my problem is that I've often seen the other way around - that peoples' behaviors modify the laws. I'm sure quite a bit could be written on that about Donald Trump who is currently in a trial that everyone knows cannot enforce any consequences to him, but for me I think the real moment it came apart was during the pandemic when I was struggling through some bureaucracy to update my car registration. I had the thought that I couldn't believe that the people who refuse to put on a mask to get groceries or whatever actually go do the nonsense that I was trying to get through right then. In contrast, covering your face with a piece of paper seemed really trivial, and yet to so many it was an affront to their identity, and so the mask mandates were ultimately rendered toothless.
John Von Neumann comes up in a lot of tech topics but he had some monstrous opinions particularly on this - he thought game theory proved that USSR and USA would go to war if both sides had nukes and recommended the USA strike first in order to win in the early years of USA almost monopoly on nukes.

Its not 'human nature'. The 'human nature' is cooperative, helpful and 'good' by instinct:

I was thinking more in terms of the Wall of Sound as shown in the article.

Why?

This is muscle memory that's built into every person who's taught to write. You should reuse that muscle memory if you can to make writing flow easier.

Sure if you were teaching people to write exclusively on these devices then coming up with something new would make sense but since we all go back and forth using the real world method makes the most sense.
> Twitter is more lenient towards specific rhetoric same with all the social sites and their affiliations

Under Musk, Twitter is lenient towards specific sorts of rhetoric that align with, or at least don't conflict with, his own leanings, and very harsh on certain other types of rhetoric, perhaps most notably criticism of Musk.
Genuine Parts (large US based auto parts retail) is similar. The folks working there are working on turbo muscle memory and navigate the system impressively quickly.
Fwiw it's almost exclusively international developers running the conversions in Kansas City. I think Greystar might be the one with the largest footprint there.
I agree and am a huge advocate for the idea that self defense is a human right.

Civilians should have a right to access to the exact same technology that a government employs with its infantry. I'm not talking Nuclear Weapons or Stealth Bombers, if a 17-year-old recruit can be trusted to operate a drone to kill human beings in a far off foreign country, law-abiding citizens should have access to the same technology. Or, alternatively, we can ban the technology, as long as the police are restricted from using it the same as civilians.
You missed the point. Driving a Tesla takes more than two steps. The door does not close itself either.

Integrated Biodiversity Assessment Tool | Remote (UK) | Full-Time | Software Engineer (Ruby on Rails) | Non-Profit | £38k-45k + 12% pension contrib + 36 days holiday

Nature is declining globally at rates unprecedented in human history. 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history. The Integrated Biodiversity Assessment Tool (IBAT) is an partnership of top conservation charities / NGOs (IUCN, UN Environment Program) that have the gold standard of biodiversity datasets. IBAT then uses the datasets, mixed with the best conservation science, to help companies understand/reduce their impact on nature and they help fund conservation, it's a win-win.

The AS400/OS400-like interfaces always seem like they should be more popular super-user interfaces. They seem best at navigating tree-like data but most OS level interfaces feel tree-like these days. I think the affordances work a little better than vim-keys sometimes. A vim-mode option or command palette would be straightforward.

But it would require people to use full size extended keyboard (function F rows, numpads, etc). Which shrinks the user base quite a bit.

Extremely logical - after a certain point, wealth is just meaningless numbers in financial computers, only expressed as the control of major organizations like corporations. Its literal unbounded power. We limited the power of kings and dukes. But we are allowing the same kind of power to those who hoard imaginary wealth that cannot be spent on actual things - it cannot be spent on actual things, because it is estimated that the amount of wealth stored in Swiss banks (leave aside derivatives etc) have already surpassed multiple times of the value of everything on the planet. So there is wealth on the planet that can buy the entire planet dozens of times over. And yet hoarding continues at great cost to the society.

I love and hate Apple as almost everyone else and have an iPad for 'consultation' only (reading, browsing, video), but on Android, you have IDEs for games dev (Godot), real android apps IDE (through F-Droid), Python, Java and C/C++ IDE (through Android Store) which are close enough of the Linux way...

So the iPad devices could handle that too if Apple allowed it...

Once Apple will enforce the European Union requirement to allow 'sideloading' on iPad, maybe we will be able to have nice things also on it.

That could also be a good thing for Apple himself. A lot of people in Europe have a bad opinion of Apple (partly?) because of the closed (walled) garden of iPad/iOS and other technology/IP which make their portable devices apart of the Android ecosystem.

Scott Galloway seems to be pretty successful. Does he attribute this to luck or talent? Genuinely curious.
That is an interesting angle to look at it from. If they're gonna keep pushing this they end up with a strong incentive to make the iPhone even more energy efficient, since users have come to expect good/always improving battery life.

At the end of the day, AI workloads in the cloud will always be a lot more compute effective however, meaning lowered combined footprint. However, in the server based model, there is more incentive to pre-compute (waste inference) things to make them appear snappy on device. Analogous would be all that energy spent doing video encoding for YouTube videos that never get watched. Although, it's "idle" resources for budgeting purposes.
> if Einstein's cosmological constant is positive, every atomic / sub-atomic particle will eventually be in its own “observable universe”

This is not correct. Gravitationally bound systems will remain bound in a universe with a positive cosmological constant. A "Big Rip" scenario, where gravitationally bound systems get ripped apart and eventually every elementary particle is beyond the cosmological horizon of every other, requires "phantom energy", i.e., a density of dark energy that increases with time.
So you bought "a thing' but you can't control what it does, how it does it, you don't get to decide what data it collects or who can see that data.

You aren't allowed to repair the "thing' because the software can detect you changed something and will refuse to boot. And whenever it suits the manufacturer, they will decide when the 'thing' is declared out of support and stops functioning.

I would say you are not an owner then, you (and me) and just suckers that are paying for the party. Maybe it's a lease. But then we also pay when it breaks, so it more of a digital feudalism.

For benchmarking ChaCha8, I ran:

go test -bench=Block internal/chacha8rand

For benchmarking AES-GCM, I edited src/crypto/cipher/benchmark_test.go:51 to add 256 to the length list, and then I ran:

go test -bench=GCM/-128-256 crypto/cipher
GODEBUG=cpu.aes=off go test -bench=GCM/-128-256 crypto/cipher

You're right that we could use AES where available in the places where reproducibility doesn't matter, although that's a second implementation to debug and maintain. ChaCha8 seems fine.
"Ultrasounds can be applied to several areas across the food industry including drying, extraction, emulsification and crystallisation – making the process faster and more efficient.", .. I think they have the tense wrong. It should read "Ultrasounds are now commonly applied .."

There always something going on at Heathrow in London.

Just wait for the mess during the summer season.
Very common on US freeways for work to be performed at night even though it's barricaded during the day. The barricades are to keep traffic off of work in progress, actual work may require additional lane closures, traffic disruptions as trucks enter and exit, and safety scales with traffic volumes. Keep in mind, for example, that the permanent closure area is not typically large enough to stage equipment. That means that equipment and supplies need to be moved in and out of a laydown yard during work, which is very dangerous during normal traffic volume.

It also tends to be the case that price is reduced by scheduling work across multiple contractors with independent scheduling... so the cost savings come at the expense of idle periods while waiting for the next contractor to be available. Not a totally unaddressable problem but ultimately fast and cheap are, as usual, opposing requirements. Funding politics can also play a role here, very common that larger projects don't have all of their funding available at once, so they may sit idle while waiting for the next set of funds.

So if you have a short attention span would you prefer watching 10 minutes of 2 hour movie or you would rather prefer watching 10 minutes of 10 seconds funny videos on TikTok?!

Different formats are meant for different purposes, in another words you can't half ass movie, documentary or whatever long form video content type there exists....you have to watch it till the end, either in one go or in multiple takes.

For example YouTube became popular because it allowed on demand video of "short" video content, short compared to TV. As kids, teens and people in general became internet dopamine addicts, they sought more faster and "instant" form of entertainment and rest is history.

The same conceptual connection can be drawn with traditional "long" form video games and casual and hypercasual mobile games. People became more lazy and and the same time more "thirsty" for dopamine and mobile devs exploited that need with casual and hypercasual mobile games.

How so?

If there are no local minima other than the global one there are convex optimization methods that are far faster than SGD or Adam. The only reason these methods exist is because deep networks is a non-convex optimization problem.

You're not going to be missing out on much. I had the first M1 Air and recently upgraded to an M3 Air. The M1 Air has years of useful life left and my upgrade was for reasons not performance related.

The M3 Air performs better than the M1 in raw numbers but outside of some truly CPU or GPU limited tasks you're not likely to actually notice the difference. The day to day behavior between the two is pretty similar.

If your current M1 works you're not missing out on anything. For the power/size/battery envelope the M1 Air was pretty awesome, it hasn't really gotten any worse over time. If it does what you need then you're good until it doesn't do what you need.
